PS D:\BaiduNetdiskDownload\vue-learn> npm run build

One CLI for webpack must be installed. These are recommended choices, delivered as separate packages:

 - webpack-cli (https://github.com/webpack/webpack-cli)

   The original webpack full-featured CLI.

We will use "npm" to install the CLI via "npm install -D".

Do you want to install 'webpack-cli' (yes/no): n

You need to install 'webpack-cli' to use webpack via CLI.

You can also install the CLI manually.
